• Capacitive Touch Sensors: − rely on the electrical properties of the human body to detect when and where

on a display the user is touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand.

• Resistive Touch Screen Technology − The Analog Resistive touch screen is a sensor consisting of two opposing

layers each coated with a transparent resistive material

− The panel then behaves as a pair of Voltage dividers with connected outputs

− Deliver cost-effective, consistent and durable performance

Devices are composed of single silicon, piezoresistive devices capable of monitoring processes in the industrial, medical, automotive, and avionics industries. Pressure sensors are composed of the following reference designs:

− Differential: Difference in pressure between two points is measured as pressure is applied to both sides of the die/sensing element.

− Gauge: Bottom side is exposed to the atmosphere, while pressure is applied to top of die.

− Absolute: Pressure is applied to the top of the die while the bottom of the die is a vacuum-sealed reference.

TM

• Pressure (p) is the force (F) applied to a unit area (A) of surface, in a gas, liquid or solid.

• Atmospheric pressure or Barometric Pressure is due to the weight of the atmosphere (air and water vapor) in earth’s surface.

• The conversions for the most commonly used units are:

• 1 atm = 101.325 kPa = 760 mmHg = 14.6960 psi

• 1 psi ~ 28” H2O ~ 70cm H2O ~ 7 kPa

Based on Magnetoresistive Random Access Memory (MRAM) technology

MRAM was once considered to be a possible “universal memory,” with write speeds approaching

those of SRAM and densities approaching those of flash memory. Replacing the RAM and flash with a

single memory to address both dynamic and static code and data storage.

This same technology is for Tunneling Magnetoresistive (TMR) Technology

for our new family of devices for magnetic sensing.

Drivers Available on request

− based upon the magnetic tunnel junction (MTJ)

− includes two electric contacts, two magnetic layers and one barrier layer.

− formed by arranging arrays of these devices into three separate Wheatstone bridges (each sensitive in a different direction)

− output voltage can be converted to digital format by the ADC.
